Brand / Profit Center

Folks - we are on BPCS 4.0.03

Currently my company has two brands, and the two brands are treated as
separate lines of business.  They are represented in the GL as separate
profit centers.  In the Item Master the ITEM CLASS field differentiates
the two brands.  We sell both brands to roughly 60% of our customers;
for each of those customers we actually have TWO customer numbers, with
different customer types and profit centers.

We would like to have a single customer number for each entity to which
we sell.  However, we still want to be able to generate a P/L and
Balance Sheet for each brand.  The expense side is straight-forward; it
is already coded manually as the invoices are paid.  Sales, Inventory
and CoGs are also painless.  But the AR and Cash piece is somewhat
troublesome; some invoices will contain both classes, and there is a
bunch of A/R stuff not associated with specific items.

Any thoughts you might have would be appreciated.
